STEAM-DETECTOR FOR FABRICS OR THE LIKE.

Specification of Letters Patent; Patented J 11116 1'7, 1919.

Application filed December 14, 1918. Serial No. 266,774.

T all whom it may concern:

Be it known that we, FRANKLINVA. PARI- NEAU and WILLIAM F. PAPINEAU, residing at Webster, in the county of Worcester and State of Massachusetts, and at New York, in the county of New York and State of NewrYork, respectively, have invented certain Improvements in Seam-Detectors for Fabrics or the like, of which the following is a specification.

This invention relates to detectors, and more particularly to apparatus of this character which is adapted for use in connection with the detection of imperfections in fabrics or the like.

One of the principal objects of the invention consists in the provision of an arrangement whereby varying dimensions, such as seams in fabrics or the like, are detected during their travel through the apparatus. Another object comprises signaling means whereby notice is given to an operator-when such imperfections pass through the apparatus. Other and further objects of the invention will hereinafter appear.

In the accompanying drawing, Figure 1 illustrates one embodiment of the invention, the electrical circuit and apparatus forming part thereof being diagrammatically illustrated. Fig. 2 is a sectional view of one of the parts of the devicetaken on line X, 'X of Fig. 1.

. In the improved detector a base or support 1 is shown. This may be of any suitable construction, and has mounted thereon a plate 2 of some such conducting material as steel, brass or the like. A carrier consisting of oppositely positioned arms 3 and 4 of approximate U-shape form are pivotally and conductively connected at one side to the plate 2. At the opposite side of the arms 3 and 1 are material-engaging members 5 and 6 in the form of rollers, suitably journaled on spindles 7 and 8, and which are adapted to move in the direction in which the fab-v with adjustable tension means 9 by the aid of which the proximity of the rollers 5 and 6. to each other is regulated. Secured to either side and at one end of the base 1 by i a strap or other suitable means are up- Wardly extending post members 10, 10. These members are each provided with resil ient contact springs 11 and 12. The springs 11 are of greater length then the springs 12, the former being adaptedto make contheir lateral movement. When an imperfec tion in the fabric, such as a seam. or the like passes through the rollers 5 and 6, the mem- I bers 3'and 1 are capable. oflateral or vertical movement, or both, and in either or both movements an electrical circuit'willbe closed by contact of the members 3 and 4 with the resilientsprings 11 and 12. At 13 is shown a contact screw secured to conducting plate 2. Binding posts 14 and 15 are provided at one end of the base 1, said posts being adapted to form terminal connections for the electrical conductors 16, 17 and 18. The conductor 18 is connected to the upper winding of a double wound relay 1 9. The lower winding of said relay is connected to a re lease key 20 by way of contact 21 of said key. The contact 21 is strap-pedto contact 22 adjacent thereto and when the relay is energized a current path is furnished through its lower winding, armature and contact and through the contacts of said key as will later appear; A visual signal or lamp 23 is'also provided and will indicate when the relay 19 is energized after the circuit is closed, as will more clearly appear in connection with the description of operation of the device, by the passage of a seam through the machine. It will be understoodthat the circuit arrangements and apparatus just outlined are individualto one machine. It is customary, however, to

provide a number of like vmachines iii a series, each equipped with similar apparatile and circuits. 'Dhese circuits and apparatus may be connected to conductors 17 and 31 and to'the conductors terminating at 33. A lbell 25 which is common to all the machines may be provided to sound an alarm upon the operation of any machine'- in the series. A master release key 26; is also. provided, and functionsto break any of the circuits which may be operated in the series. At 34 is shown a cut away portion provided in base 1. This coincides with an aperture in thefloor through which thenraterial passes in its-travel and may be furni'shed to from a source of supply, usually in an area below, through the rollers 5 and 6, and the travel of said fabric continues until some such imperfection as a seam is encountered. The members 3 and 4 with their associated equipment are of suflicient weight to remain in horizontal position during the normal travel of the fabric. The passage of the seam through the rollers 5 and 6, however, will cause them to be raised and separated and will thereby convey to the arm members 3 and 4t vertical or lateral movement, or both. In either or both movements the arm members contact with either or both of the spring contacts 11 and 12 and a path for current will be furnished by contact of the arms 3 and 4. with spring contacts 11 and 12 of posts 10, conductors 16 and 17 to binding post 15. By this means contact by either or both of said arm members is insured and a current path is provided over either or both conductors 16 or 17 to binding post 15. From binding post 15 a current path will be established over conductor 17 through contact 27 of master release key 26 to battery and return by way of contact 28 of said key, conductor 31, through upper winding of relay 19, over conductor 18, binding post 14, over conductor, shown in dotted lines, to screw contact 13 secured to plate 2. This circuit. provides for the operation of relay 19, which upon energization attracts its armature and a circuit is established over its contact, conductor 29, lamp 23, windingof relay 24, conductor 17, contact 27 of master key 26 to battery and return over contact 28 of said master key, conductor 31, through contacts 21 and 22 of release key 20, back through lower winding of relay 19 to its armature. By this circuit lamp 23 is illuminated, and relay 24 is caused to be energized. The energization of relay 2 1 provides a circuit whereby bell 25 is operated by a current. path from the closed armature of said relay over conductor 32, through said bell to bat tery, and return by way of conductor 30.

The attendant will be apprised by the sounding of a bell when a seam has passed through any of the machines. The attendant will also be apprised of the particular machine so operated by the illumination of the lamp which is individual to that machine. The lamp may be extinguished by the depression of the" release key which controls that particular circuit, and the relay which is also individual thereto will be deenergized,

breaking the circuit by which the bell is 013-,

erated. In the operation of the apparatus here illustrated and which has previously been described, the attendant noting the illumination of lamp 23 and the sounding of bell 25, depresses release key 20, causing it to break its contacts 21 and 22, thereby deenergizing relay 19 and extinguishing lamp 23. Relay 24: will in turn be deenergized upon the depression of key 20, and the circuit for bell 25 broken. Should it be more convenient for the attendant, the master release key 26 may be depressed upon the sounding of the-bell, or the illumination of any of the lamps in the series, instead of the particular release key associated with an individual machine. In such case the contacts 27 and 28 of key 26 will be broken and the lamp signal of any machine in the series will be extinguished. The circuit for the bell which is common to the series will also in like manner be broken.

The attendant after restoring the circuit conditions to normal will, at a proper time, separate the fabric at a point where the seam occurred. The fabric in the meantime continues in its passage through the material-engaging members until another seam is encountered, whereupon the apparatus will again function as previously outlined.

From the foregoing disclosure it will be seen that by means of this arrangement the attendant will be readily given notice upon the passage of the scam in the fabric as it travels through the apparatus, and by this means loss will be avoided in the production of imperfect fabric.

lVhile there is shown and described herein one preferred form of the invention, by way of illustration, it is understood that it is not limited or confined to the precise details of construction herein described and delineated, as modification and variation may be made within the scope of the claims without 100 departing from the spirit of the invention.
